Do not update CMAKE_REQUIRED_FLAGS to match CMAKE_CXX_FLAGS.

- This was a hangover from the pre-Ceres 2.0 era when we needed to
  ensure that -std=c++11 was passed to check_cxx_source_compiles() in
  FindUnorderedMap/FindSharedPtr if the user had enabled CXX11.
- Unfortunately, the same variable (CMAKE_REQUIRED_FLAGS) is used for
  both check_cxx_source_compiles() and check_c_source_compiles(), and
  thus updating it to include -std=c++11 would thus break any checks
  for C, which are made internally in the version of FindThreads.cmake
  shipped with CMake which could cause build breakage as identified
  in issue #355.

Ceres Solver

Ceres Solver is an open source C++ library for modeling and solving large, complicated optimization problems. It is a feature rich, mature and performant library which has been used in production at Google since 2010. Ceres Solver can solve two kinds of problems.

  1. Non-linear Least Squares problems with bounds constraints.
  2. General unconstrained optimization problems.

Please see ceres-solver.org for more information.
